50 Channel D2523T Helical GPS Receiver
Cost: $79.95 each
Description: The D2523T is a compact GPS smart-antenna engine board, which comes equipped with a Sarantel GeoHelix high-gain active antenna and GPS receiver circuits. The module is based around the high performance 50-channel u-blox 5 platform.
The omni-directional antenna provides great sensitivity, even when you don't have a clear view of the sky. Whether this receiver is in your pocket or under your car seat, you are likely to pickup a rock solid GPS signal.
The module operates at 3.3VDC and outputs standard format NMEA strings over the TTL/UART pins. It has up to a 4Hz update rate.
This GPS module has a connector similar to that on the EM-406, so you can use the same interface cable to connect to it.
Note: As of 2/6/2012, we are now shipping units that are based on the u-blox6 GPS engine. Both datasheets are listed below for your reference.
